FreeRTOS Theory and Practice

RTOS training can be delivered online or on-site

Description

This 3-day training class uses hands-on exercises combined with instruction to illustrate the concepts of a real-time operating system. FreeRTOS is used as an example. It is designed to bring you up to speed quickly, ensuring maximum project productivity.

The concepts and commands necessary to make effective use of FreeRTOS are described through a combination of theory and on-the-job training. Learn from an experienced trainer and take away a working knowledge of FreeRTOS and the ability to use it effectively in your own embedded projects.


Objectives Overview

Attending an RTOS training class will provide an understanding of RTOS essentials, advantages and trade-offs. Hands-on exercises will provide the practical experience necessary to use an RTOS in your own embedded system development.


Online or On-site Options

Online training is cost effective because, without travel and accommodation expenses, fewer trainees are required to cover our costs. Training can be given as a private session, and can be arranged for any mutually convenient time.

On-site training can also be provided when the number of trainees is high enough. The point at which on-site training becomes cost effective depends on the geographic location.

Course Details
Title FreeRTOS in Theory and Practice
Delivery The course is normally presented online with instructor screen sharing. On-site training can also be provided where attendee numbers make this cost effective.
Duration Modular, up to three days
Language Course material is provided in English. Instruction can be provided in either English or German.
Who Should Attend? People with an interest in, or who have been tasked with, development of a resource constrained real-time system. For example, embedded software engineers, field application engineers, project managers, etc.
Course Material and Equipment The following items are provided:
  • A bound course book, priced extra per copy
  • Low cost target hardware, typically an LPC1769 LPCXpresso Board, priced extra per board
  • A CD containing the examples and solutions
Please note, we do not permit re-use of our copyright material.
Prerequisites Attendees should have:
  • A basic familiarity with using a Windows system as an end user
  • Familiarity with embedded C concepts and programming
  • The ability to develop software using the C language
  • The ability to use an embedded compiler and embedded debugging tools
  • Basic knowledge of embedded microcontroller development boards
Pricing Private online sessions cost €3700 EUR plus shipping costs for the full three days (approximately $5000 USD plus shipping costs), offering excellent per person per day value for larger groups. The same course can be delivered on-site for the addition of the travel and living expenses incurred. Please use the form below to make an enquiry.

Public online sessions cost €1250 EUR per person plus shipping costs (approximately $1700 USD plus shipping costs) and are provided as and when enough people have registered an interest in a single time zone band. Please use the form below to register your interest.
